Successful liver retransplantation for recurrent hepatopulmonary syndrome.

HPS is defined as arterial hypoxemia because of pulmonary vasodilation as a result of cirrhotic or non-cirrhotic portal hypertension. This report describes a teenager with HPS because of primary sclerosing cholangitis/autoimmune hepatitis overlap syndrome requiring OLT. HPS resolved completely within three months of OLT, but recurred again at 12 months post-OLT following liver dysfunction secondary to a biliary stricture. She underwent a second OLT successfully and remains well two yr and three months post-second OLT. Recurrent HPS after OLT may occur because of graft dysfunction and as this novel case illustrates, retransplantation may lead to a successful outcome.
